“…In a similar manner, Corrêa et al (2019) concluded that the Seed Vigor Imaging System (SVIS®) constitutes a technique for evaluating cotton seed vigor, as there was correlation with other tests traditionally used with the same objective. Speed in obtaining results is an important aspect of the use of computerized image analysis of seedlings (Abud et al, 2017). Medeiros et al (2019) studied the physiological quality of common bean seeds with the Vigor-S® system and detected that the use of this image analysis technique allows evaluation of seed physiological potential, which shows the possibility of taking better advantage of the results obtained in the same evaluation.…”

Due to increased use of treated seeds, studies are necessary in relation to the effects of the treatments and their possible consequences on seed quality. The aim of this study was to evaluate phytotoxicity according to when phytosanitary products are applied on soybean seeds and their effect on seed physiological quality and field performance. A completely randomized experimental design was used in a 9 × 2 factorial arrangement involving 9 seed treatments (fungicides and insecticides) and two application times (60 days before sowing and at the time of sowing in the field). Moisture content was determined and tests were performed to ascertain physiological quality (germination and germination under water restriction). Root and hypocotyl length, seedling length, and vigor and uniformity indices were evaluated with the assistance of Vigor-S®. In the field, the following determinations were made: plant height at 30 and 60 days after emergence, first pod height, number of pods per plant, number of seeds per pod, and yield. Early seed treatment in the soybean crop can affect initial development of the plants, but it does not affect yield. The phytotoxicity caused by the soybean seed treatment was observed in the root length characteristic.

“…It is important to consider the benefits of image analysis for phenotyping in breeding programs. This tool has been used for species distinction (Marques et al, 2019) and for seed vigor studies (Abud et al, 2017). For maize, computerized analysis has also been used for seed vigor determination (Medeiros et al, 2018), highlighting the potential applications of this tool in phenotyping and reducing the time and costs of program procedures by decreasing the probability of human error, among other advantages.…”

Faster phenotyping tools are crucial for field progeny selection. We conducted research comparing two water deficit simulation methods on contrasting cultivars for water deficit tolerance. In a first step, we conducted two experiments: one for seed germination in sand at 10% and 70% water retention capacity, being analyzed seedling emergence and growth; other for seed germination in stress simulation by moistening the germination paper with PEG solution at -0.6 MPa, being analyzed seed germination. These experiments were used to distinguish characteristics of two maize lineages with different response to drought, being 57 - sensitive and 91 - tolerant. After that, we produced hybrid progenies from these lines at generations F1, F2, and F2:3 and applied the stress simulation by moistening the germination paper with -0.6 MPa of PEG solution. The seedling size was analyzed trough image analysis by the GroundEye® system. We could distinguish both lines and its hybrids through the stress simulation and image analysis. The results indicate that maize cultivars can be phenotyped for water deficit tolerance either 5 days postsowing through stress simulation or via image analysis of root length from seedlings germinated under -0.6 MPa. This method provides faster, more accurate, and more cost-effective methods for assessing water deficit tolerance in maize cultivars.

“…The uniformity index has great importance in the analysis of seed vigor, as a rapid and uniform emergence represents an adequate stand of seedlings in the field (Abud et al, 2017). However, this index should not be analyzed in isolation to generate information regarding seed vigor because lots composed only of poorly developed seedlings can also generate a high uniformity index.…”

Melon is a vegetable crop of food and nutritional importance whose cultivation is growing worldwide. In this sense, investments in technologies are necessary, especially regarding the quality of seeds used in the establishment of new areas. This study aimed to verify the effectiveness of the Automated Seed Vigor Analysis System (Vigor-S) in the evaluation of the physiological potential of melon seeds. Eight seed lots (four lots of the hybrid Supreme and four of the hybrid Premier) were used. The physiological potential of the seeds was evaluated through tests indicated for analyzing the quality of melon seeds associated with the image analysis by using the software Vigor-S, which included the analysis of seedlings from the germination test and accelerated aging in saturated NaCl solution. The experiment was conducted in a completely randomized design, with five replications. The results indicated the effectiveness of Vigor-S, especially when it was used associated with the accelerated aging test in saturated NaCl solution, with results similar to those obtained in traditional vigor tests. Thus, the Automated Seed Vigor Analysis System (Vigor-S) was effective in evaluating the physiological potential of melon seeds.
